LEE B. GREEN, OF

LAKEWOOD, OHIO, ASSIGNOR TO THE BORDEN COMPANY, OF

WARREN, OHIO, A CORPORATION OF OHIO VISE.

Application filed April 13, 1926. Serial No. 101,644.

This invention relates to Vises and more particularly pipe Vises.

It is one of the objects of the present invention to provide a vise that is adapted to be quickly opened and closed and for clamping pipes of various sizes.

,Another object of the invention is to provide a vise that is self-opening for the purpose of releasing the pipe.

Other objects of the invention are to provide an improved construction that will be easy to manufacture, at a low cost, and that will be durable and capable of withstanding the rough usage to which such devices are subjected in service.

Other objects of the invention and the features of novelty will be apparent from the following description taken in connection with the accompanying drawings, of which:

Fig. 1 is a side elevation of a vise embodying my invention, certain parts being broken away and other parts being shown in section;

Fig. 2 is a plan view thereof;

Fig. 3 is a front elevation; and V Fig. 4 is a section on the line 44 of F g.

Referring to the drawings, and 11 indicate side plates of a frame which are spaced apart and have bottom flanges 12 that are welded or riveted, or otherwise suitably secured on a base plate 13. Stationary jaws 14 and 15 are secured on the side plates 10 and 11, respectively, by means of the bolt 16, there being a tubular spacer 17, on this bolt, between the plates 10 and 11.

The side plates 10 and 11 are provided with grooves or ways 18, on their inner faces in which the keys 19, on the movable aw member 20, slide. One of the keys 19 carries a dowel pin 21 which projects into a groove 22, the upper end of this groove stopping a short distance from the upper end of the side plate 10, so that the engagement of thepm 21, with the end of the groove, serves to limit the upward movement of the jaw member 20. A bolt 23 extends across the space between the side plates 10 and 11, adjacent the bottom thereof, and carries a spring 24, which engages with the lower end of the movable jaw for the purpose of automatically htting the latter to the upper limit of its movement, when it is released.

On the rear side of the movable aw member 20, there is a series of teeth or serrations 25 which are adapted to be engaged by corresponding teeth 26 on the member 27, which is arranged to slide between the side plates 10 and 11 and is carried by the lower end of the screw 28. There is a circumferential groove 26, in the screw 28, and adowel pin 30, carr1ed by the member 27, engages this groove so as to secure these parts together by a connection that permits the screw to be rotated independently of the member 27. Between thelower end of the screw 28 and the bottom of the socket 31, in the member 27, there is a ball 32 which serves as a thrust hearing. The upper end of the screw 28 has a head in which a handle 34 is secured by means of the dowel pin 35.

A nut 36 is arranged between the side plates 10 and 11 and provided with trunnions 37, on its opposite sides, which engage suitable openings therefor, in the side plates .10 and 11, so that the nut is adapted to rock relative to the side plates, although held in a substantially permanent relation thereto. The screw 28 engages the nut 36 so that the screw moves longitudinally through the nut when rotated,'such lon itudinal movement also actuating the mem er 27. A bolt 38 connects the side plates 10 and 11 together, at the rear of the vise, and carries a suitable spring 39 which engages the member 27 and normally holds the teeth 26 in engagement with the teeth 25. The side plates 10 and 11 are further connected together by the bolt 39 and spacers are provided on the bolts 38 and 39', are clamped;

In Fig. 1, there is apipe P, between the stationary and movable jaws of the vise, and the pipe may be securely clamped between these jaws by turning the screw 28 so as to lower the member 27, which carries the movable jaw 20 with it, on account of the engage ment of the teeth 25 and 26. When it is desired to release the pipe, the screw 28 is slight- 1y rotated in the opposite direction, to release the pressure of the teeth 26 on the teeth 25 and the screw and nut are then rocked on the trunnions 37 to withdraw the teeth 26 from engagement with the teeth 25. This permits the spring 24 to lift the jaw 20 to its upper position, thereby releasing the pipe and opening the jaws for the reception of another pipe. So long as the member 27 is held away from the movable aw 20, this jaw may be freely moved up anddown but when the operator releases the screw 28, or its handle 34, which he will ordinarily use for movagainst which the side plates permit the teeth 25 to slide over the teeth 26.

The screw 28 is then rotated to further depress the jaw 20 to securely 'elamp the pipe;

From the foregoing it will, be seen that I have provided a comparatively simple form of construction that will'permit the jaw :20 to be quickly moved either to its closed or open position, byrocking the screw 28 and the nut 36 onthe trlinnions 37th disengage the teeth 25 and-T98.
